On the following URL this string appears to be translated :
http://carolina.mff.cuni.cz/%7Etrmac/fedora/translate/initscripts/de.po
Also, the following command (on Fedora Core release 4) :
strings /usr/share/locale/de/LC_MESSAGES/initscripts.mo |grep -i "um in den"
return the following output :
"cken Sie 'I', um in den interaktiven Start-Modus zu gelangen."
(the output looks scrambled on my screen, probably because of the German
Umlaut-character).
Does this bug still occur for you with Fedora Core release 4?
